Application tiled May Z7,

To all whom t may concern:

Be it known that I, WILLIAM JOHN WHIT- ING, Works-manager, a subjectofthe King of Great Britain, residing at Douglas road,

lI-Iandsvvorth, near Birmingham, England,

ment with the barrel and hammer when the revolver is opened. As appliedto a certain type of automatic revolvers provision is also made forinsuring the rotation of the cylinder in the proper direction when beingfired. In conjunction with the various locking devices means areprovided for simultaneously d'isengagng the same from the cylinder,conslsting'of a push-piece Working through the barrel-strap, hereinafterfully described, and represented in the accompanying drawings,in whichthe application of the invention to automatic revolvers of theWebley-Fosbery type yis represented in Figures l to 5, while Figs. 6 to1l show its application to an volver.

Fig. 1 is an elevation of the revolver closed, with a part inlongitudinal vertical section to show the disposition of the alinement,direction, and locking studs, and the push-piece by which they aredisengaged from the cyli'nder when it is required t'o dismount thelatter. 'This view represents the direction and locking stud inengagement with a notch-cylinder, While the alinement-stud is raisedclear of the said cylinder. Fig. 2 is a sim ilar view to ZFig. l, butwith the revolver opened and the cylinder held in alinement with thebarrel and hammer by the stud engaging in one of the rearward channelextensions of the zigzag race. Fig. 3 represents a cross-section of thecylinder and'eXtension-'rib upon thedotted line x, Fig. 2. Fig. 4 is anunder side plan of the extension-ribs, showing the disposition of thetwo studs and the jointed arms on which theyvare mounted. Fig. 5 is aView showing, upon an enlarged scale, the arrangementcof ordinary ref7oo,592,l dated May 2o, Iooa. Serial No. 62,106. (No model.)

the alineinent, direction, and locking studs, with their arms, springs,and push-pieces in the positions they normally assume when the revolveris opened. Fig. 6 represents, partly in elevation and partly inlongitudinal section, a revolver. Fig. 7 is a similar View. to Fig. 6,but shows the revolver opened and the cylinder locked both againstlongitudinal movement for preventing the withdrawal'of the samefromoiits axis and also against rotation to insure that one of its chambersshall remain in'alinement with the barrel so long as the weaponisopened. Fig. 8 is a crosssectionof the cylinder and top strap uponthe.

dotted line az', Fig. 7;'and cross-section of the ysame through thefront of the cylinder on the dotted line to2. Fig. 10 represents anunder side plan of the barrel-strap, showing the arrangement offthelocking device fitted therein'. 1 Fig. 11 represents, upon an enlargedscale and partly in elevation and partly in longitudinal verticalsection, a part of the said revolver, showing the cylinder-lockingdevice in the position itis made to assume when the weapon is closed, soas to leave the cylinder free for. rotation.

Fig. 9 is another In the automatic revolver represented in.

Figs. l to 5, the rotation of the cylinder by a zigzag"race beingconstrained to work over a fixed peg on the bed or body of the revolverwhen the said cylinder is forced backward by theaction of recoil'after adischarge, ais the cylinder; d, the flat-bottomed zigzag race thereof;b, the'bar'rel-strap of the barrel b'; c, the standing breech, and t'the 'xed peg on the frame for rotating the cylinder when the lattertravels back under the recoil.l

The alinement device direction-studs used in conjunction with thecylinder-rotating mechanism are arranged within a clearance or sinkingb4 in the under side of the lbarrelstrap, and the studs o and p arecarried, respectively, by a pair of arms or levers o p Whose inner endswhich overlap are jointed by or turn upon acommon center-pin q,c'rossing the clearance b4, p2 are provided between the .top of theclearance and the levers for depressing both limbs for. .taking thestuds into their engaging posi- .tions when the weapon is opened. 'Asmall view, but taken' While suitable springs o2v pusher r works throughthe top of the barrelstrap,`and itsinnerend fr' impinges in common uponthe overlapping extensions of the two arms, the arrangement being suchthat when the pusher is depressed the arms are rocked and the studs oand p are respectively lifted clear of their engagements withthecylinder, which may then be-dismouhted or withdrawn from i'tssupport.

The tip end 03 of the arm 0', which carries the alinement-stud o,extends into the eye b3 at the end of the barrel-strap, so-that on theclosing ofthe revolver the said tip comes upon the shoulder-of a 4notchc formed in the .face of the'standing breech c, and is'therebylifted, soas to keep the alinement-stud clear of the rearward channels a3 in thecylinder, which is thus freed for rotation;

The stud p, which has a straight shoulder 2o p3 to engage thecylinder-channels a4 and an inclined or wiper face p4, is designed forsetf ting the cylinder in such a position relative to the fixed peg soas to insureils rotation in the proper direction, and lin additiontothis the said stud p also fills the function of a cylinder-lock forpreventing the withdrawal of the cylinder from its support when therevolver is opened', until the push-piece r has been depressed. Forthispurpose the part of the cylinder that passes under the stud 19 isprovided with the rearward channels a3 and intermediate ofthe forwardchannels u.l with aseries of peripheral curve-bottomed recesses s, whichwill freely pass the stud as the cylinder rotates, but which whenengaged by the said stud dropping therein, as represented in Fig. 5,efectually prevent any 'movement of the said vcylinder longitudinally,so that to release the cylindcr'for dismounting after-the revolver isopened the push-piece has to be operated tlift .the locking-stud clearof the said recesses s.

In the ordinary revolver (illustrated in Figs.

6 toll) the device for locking and alining the cylinder a to the barrelb consists of a single rocking sprin g-limb 19', located within asinking b2 in the underside of the barrel-strap b and pivoted at pzata'point between the forward end and its middle, while the tip p? of theextreme rear end extends into the eye' .b3 at the "end of the saidbarrel-strap and is adapted to be engaged by the shoulder of a notch c',cut in the face of the standing breech c. The forward end p4 of the saidlimb is acted upon bya push-piece l1*,working through and projectingabove a hole in the barrelstrap, while rearward of the joint p2 isadepending tooth p, adapted to engagehvhen the weapon is opened) with oneor o ther of a series of small notches-s, formed around the periphery ofth'e cylinder in radial alinement with the axis of the cylinder-chambersa' and whereby the cylinder is locked to the barrel 'with one ofitschambers in proper alinement. The spring p5, .which automatically takesthe tooth pinto engagement when the tip end of the lever is freed fromthe notch in the standing breech, is located between the top of thelever and the roof of the sinking in the strap.

The cylinder is freed or disengaged from the lock for rotation when-therevolver is closed by the shouldered notch of the breech impingingagainst the extending end of the spring-lever and lifting the tooth outof the notch. When closed, a chamber of the cyliuder is kept inJalinement'wit-h the barrel by the usual means provided for that purpose,said means in the present case consisting of a tooth t', connected withthe trigger-t and working up through a slot in the frame or body b4 ofthe revolver t engage the undermost notch s, which is held in thedesired positionby the stud p engaging with the topmost notch, it beingunderstood that the said stud p is not lifted clear of the said topnotch until the undermost notch has been passed into engagement with thetrigger-tooth t' by the act of closing the revolver.

The cylinder-.may be provided with a series of shouldered lumps or snugsu, arranged, respectively, over the chambers and alinable 'with thenotches, the same being adapted to take into and engage the shoulders ofgrooves or channels fu. u?, cut across the under side ofthe barrel-straph and the top of the frame or body b4, so as to prevent the cylinderbeber is in line with the barrel.

To dismount the cyiinder after the revolver has been opened, thepush-piece r first has to be depressed to rock the spring-limb and liftthe tooth p out of engagement with oneof the notches s, afterwhich thecylinder is slightly turned, so as to clear-the top lump u'from thegroove u in" the rib, when the said cylinder lcanthen. `be withdrawnlongitudinally from o its support.

f Having fully described my invention, what `I desire to claim andsecure by Letters Patent`is l l; In a revolver, the combination with aremovable cylinder provided. with recesses, of acylinder-locking catchadapted to successively engage said recesses, and a hand-operated pusherfor acting on said catch to disn engage same from the saidcylinder-recesses,

substantially as set forth. y
